After an assessment the nurse concludes that a client is experiencing infective endocarditis. What finding is consistent with this diagnosis?

Infective endocarditis produces a variety of peripheral vascular manifestations due to septic emboli and deposition of immune complexes. These clinical markers, combined with systemic symptoms like fever and new cardiac murmurs, are essential diagnostic findings that indicate the microbial destruction of cardiac tissue and subsequent systemic involvement. A. These described lesions are known as Janeway lesions. They are small, painless, erythematous macules found on the palms and soles. They are a classic peripheral sign of infective endocarditis caused by septic microemboli from heart valve vegetations, representing a significant finding in a comprehensive cardiovascular assessment for this infection. B. Jugular vein distention (JVD) is a sign of increased central venous pressure, typically associated with right-sided heart failure or fluid overload. While severe endocarditis can eventually lead to heart failure due to valvular destruction, JVD is not a specific or hallmark diagnostic sign of the infection itself. C. Pleuritic chest pain that worsens when the patient is in a supine position and improves when leaning forward is the classic presentation of acute pericarditis. In contrast, endocarditis pain is often absent or related to systemic embolization rather than the positional inflammation of the outer pericardial sac. D. A pleural friction rub is a raspy sound heard on auscultation when the pleural layers are inflamed, such as in pleurisy or pneumonia. A "pericardial" friction rub is heard in pericarditis. Neither is a characteristic assessment finding for infective endocarditis, which primarily affects the internal valves and endocardial lining.
